'We’ve known for a while that heavy drinking can increase your risk of developing dementia.

'This study suggests that alcohol abuse disorders may be responsible for more cases of early-onset dementia than previously thought.

'But because this study only looked at hospital admissions, and was based in France, we would need further research in other healthcare settings and countries to fully understand how many cases of early-onset dementia are caused by alcohol abuse.

'This study in no way suggests that moderate alcohol intake could cause early-onset dementia. The study doesn’t change the advice to stick to no more than 14 units of alcohol a week. Anyone concerned about heavy drinking should visit their GP to discuss ways of cutting down and the support on offer.'
